== are used as terminators:
-- for core expressions, and
== for terminating a 'running' or 'jogging' series of Hoon expressions.
-- rune is used to indicate the end of a core expression.
|^ runes are used to create cores that can have arbitrarily many arms. When you have defined all the desired arms in a core expression (using the
+* runes), use
-- to terminate the expression.

== rune is used to indicate the end of a 'jogging' or 'running' series of Hoon expressions (runes that take a variable number of arguments).
Certain runes are used to create expressions that may include arbitrarily many subexpressions. Such expressions are terminated with the
== rune. For example, the
:~ runes are used to create a cell of any length. (The latter is just like the former except that it adds a null value at the end of the cell.) For another example, the
%= rune used used to make arbitrarily many changes to a given wing value.
